Silver Nano inks vs Flakes inks
Silver nano inks
• Particles size : < 50nm• Low sintering
temperature• Light absorption suitable
for photonic curing• Suitable to address
different printing methods
• Resistivity : < 3,5 µΩ.cm• Flexible: conducive even if
folded
Silver flakes inks
• Particles size : > 2µm• Resistivity : more than 15
times the silver bulk resistivity
• The ink is just cured

Nano inks vs Flakes inks Curing comparison
SILVER FLAKES
Before curing: large particles
with lot of empty space.
SILVER NANO
Before curring : high density
of particles without any
curing.
After curing After curing

How to outperform ITO film?
Coating of ZnO
AFM Silver nanowires AFM Silver nanowires+ ZnO
ZnO nanoparticles Very high efficiency in ETL layer Decrease the roughness of silver
nanowires Increase the conductivity of silver
nanowires
Results :Transmission > 85%R = 20 Ω/sq

ITO limit and the solution
The Indium Tin Oxyde (ITO) as some limit:
• ITO: from rare metal
• ITO: not-foldable
• ITO: vacuum deposition (PVD)
The solution coming through printed electronic and ink:
• 1 layer of Nanowire covered by one layer of AZO
• 1 layer of combined solution of Nanowired and AZO
• 1 printed grid of silver covered by one layer of AZO ClearSilver

V3.0.18122014 Genes’Ink proprietary information
The goal of this project is to develop an industrial solution for the production of large R2R inkjet printed electronics.
– CLEARSILVER will produce a flexible and Transparent Conductive Films (TCF) for OPV and OLED lighting
– The solution proposes inkjet printed Ag grid covered with ZnO nanoink onto polymer films

Enable the use of nanoinks at an industrial scale:
In the industry, there is no process for mass production, only lab quantities are available.
Genes’Ink capacity will be raised up to > 10 000 litres per year (2 millions m2).
Develop an industrial inkjet printing solution with:
A high printing speed of 40 m/min compared to few mm/min of current lab machines. We are now at 10 m/min on a pilot KSCAN PE300 KT printer (TRL6).
A high resolution, less than 10 µm width ± 1 µm on large area (1 m web). Achieved actual resolution is 50 µm ± 2 µm (320 mm web).
A capacity to print at high speed inks containing between 15 to 40 % of solid content.
